"Still, economists on both sides tend to agree that the minimum wage itself isn't that big of a factor for America's working poor. For one thing, many of the people earning the minimum aren't poor at all; they're teenagers or middle-class part-timers looking for extra income.
The working poor tend to earn more — because they have to if they're supporting a family. For them, the benefit of recent minimum-wage hikes has been relatively small, especially when compared with other anti-poverty programs such as the federal Earned Income Tax Credit."
